Sukumaran observed; "Today the Dalit are in the shade of many shelters. A few have attained distinction in society. They keep on the struggle for more opportunities. But forgetting the past, its memories and its message, in fact, hinders the total liberation of the Dalits". Sukumaran asserted, " the Datits should proud of themselves and proudly re-affirm their own culture". He was the most popular and influential leader after Ayyankali. He fought against the caste notions as a rationalist and his crusade, which been as a ripple, gradually extended nationwide.
